EAST BAY MUD is located in OAKLAND (ALAMEDA CO.). The primary water source type is Surface Water. This water system services 380,450 connections, and serves a total population of 1,379,750 individuals.
Of the 86 chemicals tested for in your water system, 17 chemicals were detected, and 12 average annual chemical findings exceeded their MCL, though this dos not necessarily constitute an MCL violation \(^*\).
In the plot below, the Maximum Contaminant Level (MCL) is shown as a black horizontal dashed line. Each contaminant tested for in your water utility is represented by a vertical bar, and the height of the bar indicates the level of contaminantion of that sample. Any contaminant at or exceeding the black horizontal dashed line indicates contaminated water, and values under the black line indicate safe drinking water.
Hover over the bars to see more information for each contaminant.
69 other chemicals were tested for and NOT detected, including:
1,1-DICHLOROETHANE, 1,1-DICHLOROETHYLENE, 1,1,1-TRICHLOROETHANE, 1,1,2-TRICHLORO-1,2,2-TRIFLUOROETHANE, 1,1,2-TRICHLOROETHANE, 1,1,2,2-TETRACHLOROETHANE, 1,2-DICHLOROBENZENE, 1,2-DICHLOROETHANE, 1,2-DICHLOROPROPANE, 1,2,4-TRICHLOROBENZENE, 1,3-DICHLOROPROPENE (TOTAL), 1,4-DICHLOROBENZENE, 2,3,7,8-TCDD (DIOXIN), 2,4-D, 2,4,5-TP (SILVEX), ALUMINUM, ANTIMONY, ARSENIC, BARIUM, BENTAZON, BENZENE, BERYLLIUM, BROMIDE, CADMIUM, CARBON TETRACHLORIDE, CARBONATE ALKALINITY, CHROMIUM (TOTAL), CIS-1,2-DICHLOROETHYLENE, COPPER, CYANIDE, DALAPON, DCPA (TOTAL DI & MONO ACID DEGRADATES), DICAMBA, DICHLORODIFLUOROMETHANE (FREON 12), DICHLOROMETHANE, DINOSEB, ETHYL-TERT-BUTYL ETHER, ETHYLBENZENE, FOAMING AGENTS (MBAS), HYDROXIDE ALKALINITY, IRON, LEAD, M,P-XYLENE, MANGANESE, MERCURY, METHYL-TERT-BUTYL-ETHER (MTBE), MONOCHLOROBENZENE, NICKEL, NITRATE (AS N), NITRATE + NITRITE (AS N), NITRITE (AS N), O-XYLENE, PENTACHLOROPHENOL, PICLORAM, SELENIUM, SILVER, STYRENE, TERT-AMYL-METHYL ETHER, TERT-BUTYL ALCOHOL, TETRACHLOROETHYLENE, THALLIUM, TOLUENE, TRANS-1,2-DICHLOROETHYLENE, TRICHLOROETHYLENE, TRICHLOROFLUOROMETHANE, TURBIDITY, LABORATORY, VINYL CHLORIDE, XYLENES (TOTAL), ZINC.
Because they were not detected, these chemicals are not included in the chart above.
When a measured contaminant exceeds the MCL, a set of regulatory actions is taken to improve water quality. All regulatory actions taken during the period of this report are shown below:

This Consumer Confidence Report was automatically generated, and hence, the data herein may be incomplete or inaccurate. The authors claim no liability or responsibility for data quality. This data represents the average result of all post-treatment samples from the period from 2019-01-01 to 2019-08-19. For questions about your local water quality, contact your water system.
Maximum Contaminant Level (MCL) refers to the highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs are set by the U.S. Environmental Protection Agency (U.S. EPA).
Public Health Goal (PHG): The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency.
If a contaminant has an exceedance of 999%, this indicates a detection for which the MCL is 0. Any number divided by 0 is infinite, thus it is assigned an arbitarty large value (999) to indicate exceedance.
In the barplot and table above, XMOD indicates additional qualifiers on the data.
